Silicon Laboratories is bringing the benefits of digital performance and integration to mechanically tuned analogue radios with the introduction of the Si4830 AM/FM receiver. The receiver IC reduces product design time and system cost and streamlines manufacturing for a range of radio products such as portable radios, boom boxes, clock and lamp radios. This CMOS, wheel-tuned, radio receiver IC offers an AM/FM radio from antenna input to audio output in a single small chip. Using the IC eliminates the need for external microcontrollers, AM/FM filters, tuning inductors and other components, reducing material and labour costs. Developers need only add an antenna, mechanical-tuning and off/on volume wheels, amplification and two AAA batteries, and the receiver becomes the platform for a low-cost radio design. The receiver targets radio manufacturers worldwide, especially those based in China. The receiver requires only twelve surface-mount components within a compact, 20mm2 single-side board area. The receiver supports European EN55020 compliance and delivers simple, accurate, and reliable tuning for worldwide FM bands from 64 to 108MHz and AM bands from 520 to 1710kHz.
